For those who do have a foam mat there or are wanting them there are some that are made in Taiwan and have passed all the safety standards re: the chemicals that other mats have put in them. As all the articles you will read say is that its the ones made in China they are concerned about. From personal experience I know the ones from the reject shop are very strong smelling that can knock someone over from just opening the packet a little. The one we got from Taiwan 2 years ago does not and did not have a smell at all.
